A further object of this invention is the provision of a device for dispensing liquid by weight per unit volume and providing a continuous record of the liquid dispensed.

A still further object of this invention is the provision of recording means in a device as mentioned above which is adapted to make a permanent record of all the liquid dispensed and separate records of the individual dispensations.

A still further object of this invention is the combination with a supply source and means for deliverin liquid therefrom of means for receiving t e liquid and recording its weight as it passes therethrough.

A still further object of this invention is the provision of means and in a device as described above, which is adapted for automatically shutting ofi the supply of liquid to the receiving means when a predetermined quantity by weight has been delivered thereto.

A still further object of this invention is the provision of a receivingchamber for use in dispensing liquids which is mounted for movement about a pivot point and adjustable with respect thereto so as to provide that a predetermined quantity of the liquid may be delivered thereto.

Another object of this invention is .to rogeneral to liquid I .vide a device by means of which a stan ard United States gallon chamber is mounted with respect to a pivot point and means for receiving a larger body of liquid whereby a balance may be secured between the two bodies of liquid so as to operate means for closing off the supply when a predetermined quantity has been delivered from the source.

A further object of the invention is to pro vide means in combination with the preceding combination adapted to make a permanent record of the weight of all liquid delivered from a source as well as separate records of the individual quantities delivered therefrom.

These and many other results appear from the following disclosure and are means of my invention.

This invention resides substantially in the combination, construction, arrangement and relative location of parts as will appear below.

In F the present method of dispensing liquids, such as for instance gasoline, itis well known that the product may vary under different conditions of temperature and pressure as well as its specific ravity. Thus, some gasoline; are much lighter and more volatile than other rsolines so that although a given volume of liquid is purchased, the quality of the liquid not uniform. One of the standard 1 iethods of specifying gasoline, is todenote its weight in pounds per gallon. Jobbers and the like who purchase large quantities or? gasoline specify as one method of indicatin the quality of the gasoline. pounds per nda rd gallon which the gasoline must weigh. The orlinar consumer however, at th present time who buys in small quantities has no way to check up the value of the gasoline which he is purchasing and may merely see that he gets a given volume of gasoline.

The invention about to be described. provides a relatively simple, automatic device for accurately and quickly dispensing a given volume of liquid and at the same time. producing: a perm ai'ient record of the total weight of the volume dispensed. s will appear later. the device is so arranged i. ,at a standard gallon of gasoline is ha .ced against a given predetermined ruuintitv of gasoline and in so doing. a recordii'ig' mechanism is operated to provide a permanent continuous record of the weight of the quantitv measured as well as a permanen individual record of the particular quan. dispensed.

Referring: to the drawings a suitable support 1 such. a floor plat-form or concrete base. is provided below which is mounted for instance below the level of the ground, a suit able source of supply 2 for the liquid from which it dispensed through an intake pipe 3 by means oi any suitable type of pump at. I have shown in connection with a single source and a single pump. two dispensing devices as will be shown bv taking Figs. 1 and 1 together.

It is of course evident that this is not a nece: rv combination since one or more than two devices mav be. supplied from a single pump. The operating" 1 chanism for the pump is she a. as comprising; a driving gear 8 and a near rack 7 co nectcd to the piston pump. T particular construct on of the pump is no part of this invention since any suitable or desirable pump may be emploved in cotmcction with the rest of the apparatu Deliver pipes 5 and 6 lead the gasoline from the pump to the dispen ng apparatus. A suitable valve 9 is provided in the del very lines. The dcliverv lines are connected to a short lena't-h of pi e 10 which projects into a suitable container 1?). The valve 9 is provided with a lever 11 to which has been piv tall v connected a nuinual operating; bar and v handle 12. container 13 which may be made in any cross section and of an;. material as glass, metal and the like is clamped by means of the rods 14 between two end members 22 and 15. A large opening 22 is pro vided in the member 15 and a flexible bottom is provided for the chamber 13. The seats in the members 22 and 15 and the flexible bottom 20 are all united together and to the chamber 13 so as to provide liquid tight connections. Mounted on the upper end plate 22 is a suitable air vent 22 for maintaining atmospheric pressure within the container 13. Pivotally mounted at 21 is a rod 17 which is threaded at its outer end and has mounted thereon a weight 18 for rotation on the threads. The end of the rod is connected by means of a flexible link 19 to the rod 12. is shown in Fig. 8 secured to the rod 17 for rotation therewith a short arm 17' which is provided at its end with a roller or cam follower 18, adapted to contact with the cam surface 70 on the chamber 70. The operation of this equipment will be described later.

Secured in the bottom of the flexible member 20 near the center thereof. is a delivery connection forming a liquid tightunion therewith and delivering: into the chamber. The whole structure is supported by means of the vertical uprights 16 secured to the bottom plate member 15. The chamber 70 is connected to a delivery pipe 71 which is mounted in a packing gland formed by means of the threaded thimble 71' mounted in the chamber 70. A chamber or container is secured to the outer end of pipe 71 and is of such size as to he a United States standard gallon. This container delivers into a flexible hose through a control valve 526 and has on its outer end a delivery nozzle 25'. Also secured to the container 2 is a ho r or rod 37 adapted to slide in a bracket 73 secured to the base of the container 70. A plurality of plungers 44 are mounted within recesses in the rod or bar 37 and have on the ends raiser numbers indicating the number of gallons that the device is adapted to measure out when that particular plunger moved into alignment with an operating rod ell) as will be described later (see Fig. 3). A. handle 36 is provided for moving the chamber 2% towards and away from the pivot point at. 38. The packing gland 71 provides a light tight connection between the chamber and the pipe 71 and serves in connection with the rod 37 for supporting the (he mbc r 24.

The uprights l6 serve to support by means of the brackets 32 the. container or casing 32 within which is mounted the me hanism for operating the recording devices. m w able member 39 is slidablv mounted in the casing: and is supported at the outer en: of the levers (i2 and (33 by means o! the lllYulS T5 and 7% respectively. It will be noted that the pivot pin or number 38 is secured to the movable member 39. J ournaied in the casing 32 and extending therethrough, is a shaft 27 having mounted on opposite ends, the pointers 28 and 29 respectively. A soriber member 30, which will be described in detail later, is mounted on the pointer 29. Supported on one side of the casing 32 is a bracket or frame work 31, in which is journaled the tape rolls 33, 34 and 35. An indicating scale is shown at 28' for the pointer 28 and a similar scale is shown for the pointer 29.

In Figure 4 is shown a cross sectional view ofthe recording devices. The scriber 30 comprises a hollow casing 41 within which is slidably mounted a pointer or scriber member 43 which is forced to the left by means of the spring 42. One of the recesses in the rod 37 is shown as well as one of the plungers 44 on the outer end of which is provided a number representing the particular number of gallons of gasoline which will be measured when that plunger is in alignment with the rod 40. Referring to F ig. 3 it will be noted that the rod 40 passes through a hole in the member 37 into contact with the plunger in the recess adjacent the hole. The plate 46 shown in Fig. 4 and more clearly in Figs. 11 and 7, is providedwith an arcuate slot in which the scriber 43 travels in contact with the outer tape indicated as R. is fed from the spool 33. A tape R (see Fig. 2) is fed from the spool 34 and passes down along with tape B through achannel formed by the plate 46 and the plate 81 (see Fig. 12) directly in back thereof. In actual operation a tape having a double carbon surface will be provided between the two ribbons R and R so that the recording devices will make a record on each of the tapes.

Journaled in the frame 31 as shown in Fig. 2 on the same shaft with spool 35 (see Fig. 12) on which the permanent record R" winds up, is a ratchet wheel 47 which cooperates with the vertically slidable pawl 48 (see Fig. 11). The operation of this ratchet and pawl Will be described later.

As more clearly shown in 3, there is disclosed the pivots 50 and 51 in which are journaled the short pivot rods 52 and 53. It is pointed out that the shafts 52 and 53 extend completely across the casing 32 and are in the same plane but separated from each other as will appear in Figures 5 and 6. These shafts are shown broken in Fig. 3 for sake of clarity but they actually extend completely across the casing and parallel to each other. Mounted on these shafts 52 and 53, are the members 54 and 55 respectively. the latter of which has one-half of its surface cut with gear teeth as is shown in Fig. 6. These teeth mesh with the gear 27' which is mounted on and secured to the transversely extending shaft 27. Attached to the members 54 and 55 are the flexible connections 58 and 59 which J are respectively connected to the levers 62 and This tape 3 weights tend to maintain the recording maxi' mum in normal position and to return it thereto after a measuring and recording operation.

It will be seen then that the cover member 39 supports the weight of the liquid in the chamber 13, chamber 70, pipe 71 and chamber 24 on the pivot pin 38 and that this weight is transmitted through the levers 62 and 63 to the members 54 and 55 respectively to cause them to rotate against the action of the weights 5'7 and 56 respectively to thereby cause a displacement of the shaft 27 and its pointers an amount proportionately to the weight of the liquid in the said chambers.

In Figs. 7, 11 and 12 is shown the spool support 31. It comprises the two members 31 in which are rotatably mounted the spools 33, 34 and 35. These brackets support the plate 81 and the plate 46 which are parallel to each other and sufficiently separated so that the tapes R and B" may pass downwardly therebetween as is shown for instance in Figs. 2, 3 and 4. It will be noted that the plate 46 is cut away on the line 46 so that the outer tape R may be pulled down after a recording operation and torn oil to provide a permanent independent record of the shape shown in Fig. 10. The vertical lines represent a number of gallons which have been dispensed in a single unit and the curved line C. is a record indicating how accurately the given volume for which the device has been set to deliver approaches the proper weight for that quantity. Thus, in the record shown in Fig. 10 a volume of sixty gallons having been dispensed, it is evident that the gasoline sold was somewhat heavier than the standard weight of that quantity of gasoline since the machine is nominally adjusted. so that the record produced will exactly terminate on the line representing the particular number of gallonswhich the machine has been previously set to deliver. The record in Fig. 9 is that made on the tape R and represents a continuous record of the total number of gallons dispensed over a period. The vertical movement of this tape R is provided by means of the ratchet wheel 47 and the pawl 48 and this movement is represented by the vertical distance between two adjacent curved lines. The record is shown at B. and i the line drawn starting from the point Zero and moving towards the right represents the quantity dispensed while the return line does not represent anything except that its extreme left hand end does indicate the quaniii) iii]

tn of liquid left in the device. \Vhen this return line. however moves completely back to Zero the indication is that the measured gasoline has been completely removed from the machine.

The operation of machine or dispensing device is as follows The no 26 is closed and the chamber 2% is ni'ved the proper distance away from the pivot point 38 means of handle to adjust the up iaratus for the particular qu' .ity of gasoline which it is intended to dispense. This movement of the chamber causes the pipe 71 to slide in or out of chamber Y and the arm 37 to slide in or out of the bracket 73, depending upon the quantity of gasoline to be di pensed. As shown in Fig. u the device is adjusted to dispense the maximum amount of gasoline and the last plunger l l has been brought into alignment with the rod 40, Fig. 3), and s held in proper position by the assage oi the rod -10 into the hole di e tly in line with the plunger as. For purposes of illustration we will assume that the device is adapted to g5 dispense titty gallons 4 asoline when the red l0 s -n at gninent with the last plunger 1 ls i i ne numeral will be provided in rei the end of this plunger. The device is new ad'usted to measure out lifty gallons :u) of gasoline and the recording apparatus is now at Zero. The pump 4 is then operated to deliver gasoline to the chamber 13 through pe 5. The gasoline runs down through e 71 and fills t pi he tank 2%, pipe '71 chainor :0 and overflows into tank 13. As tank 13 fills. the \vei of the gasoline pressing it .Zltlljf tends rotate the structure 'ue pivot pin 38 raising the tank 24 upwardly. "fv hen fifty gallons of gasoline have been delivered to the chamber 13, the device will have rotated about the pivot pin US so 5 the outer ri 'nt end of the chamber 4'0 (see Jig. T) will have moved downwardly amount to permit the weighted l.) arm 1? to rotate about its pivot 21 and operate 9 9 to shut oil the supply of gasoline.

' the total weight of .icrs will have gradually war ly against and to raise l to which the 58 respectively rotation of the amount. so that the e. a record on both the iletion oi the nber the with it spool 35 i 1i- .11 to be .W-uno up a sum.

1 35. The movement epresented by the two parallel pairs record R By may be caused to stamp the number 50 on both tapes. The measuring operations have now been completed and the gasoline may be delivered from the measuring device through the hose 25 on opening valve 26. It may be noted also that the scales 2S and give visible indications of the amount of gasoline being; dispensed. As the tanks empty and the weight therein reduces, the apparatus pivots about the pin 38 and returns to its nortion. The operator of the device pulls t e tape P. down sufficient and tears it oil against the cutting edge to to give the nown in Fig. 10. It may be well to point out here again that a double carbon sur- :""-:ce tape provided between the two tapes so that a record will be made on each of them. 5 he" been shown in the drawings for arity.

l in hack of the operation of the gasoline enters the .zinird gallon tank 24:; its the lever extending to the of the pivot pin 38. is adapted to balance weight ot' the asoline in chambers 70 ng through a shorter which is ecr arm to the right of the pivot pin 38. It be noted that the center of the pivot pin to the left of the center of the tank 13 :3: that the weight of the gasoline in this tank iii acting through a shorter lever arm to balonce the weight of the quantity of gasoline in the container Ql which is of a standard vc-lume. The adjustment of the device for dispensing dilierent quantities of gasoline is provioed by varying the length of the lever arm through which the weight of the gasoline in tanl :24 operates.

It 'ident that many modifications and changes in the details of construction and arrangement or parts will. readily occur to those skilled in the art. It is, of course evident that after the device is constructed it must of 'ty be adjusted so that it will properly measure oil a predetermined quantity of gasoline and make a correct record thereof. The indicating apparatus may be readily adjusted by means of the weights 56 and 57 and the point of shut oil of valve 9 can be controlled by moving the weight on the rod 17.
